Light of wavelength 648.0 nm is incident on a narrow slit. the diffraction pattern is viewed on a screen 57.5 cm from the slit. the distance on the screen between the second order minimum and the central maximum is 1.05 cm . what is the width of the slit in micrometers (μm)?
thermal energy flow from one system to other due to temperature gradient
when temperature gradient occurs it will have flow of energy from one to other
so here we can say
a calorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same temperature.
when the velocity of a mass on a spring is zero, the acceleration is at a maximum .
there are many many of those. here are a few:
-- i get paid on my job.
-- dates numbered from 1 to 28 .
-- i receive a social security check.
-- i receive a small pension payment from bp.
-- i make payments on my home mortgage and car insurance.
-- if there is any balance due on my credit card, i pay that too.
note: any answer that says anything about the moon is incorrect. the moon's period of orbital revolution is 27.32 days, and the period of its full set of phases is 29.53 days, so there's nothing about the moon that always happens once and only once in a month. for example, there can be either one or two new moons or full moons in the same month, and although it's rare, mathematically difficult, and unusual, you can have a february with no new moon in it, or a february with no full moon in it.
